Which of the following about arterioles is true? They have smooth muscle cells in their walls that control diameter and resistance. Their total area is larger than that of capillaries. They are called capacitance vessels because of their capacity to stretch. Their mean blood pressure is higher than that of arteries. Their velocity of blood flow is higher than that of arteries.

All correct about arterioles Except one. Play a major role in regulating local blood flow. Play a major role in regulating arterial blood pressure. Have a smaller wall lumen ratio than have arterioles. Offer more resistance to flow than capillaries.
Shaiju T.
Blood flows more slowly in the arterioles than in the artery that supplies them because the arterioles a. have thoroughfare channels to venules that are often closed off, slowing the flow of blood. b. have sphincters that restrict flow to capillary beds. c. are narrower than the artery. d. collectively have a larger cross-sectional area than does the artery
